IRA R. COHEN, OF NEW YORK, N. Y., ASSIGNOR TO THE MEYROWITZ MANUFACTURING 00., A CORPORATION OF NEW JERSEY.

GUARD FOR EYEGLASS-MOUNTINGS.

To all whom-it may concern:

Be it known that I, IRA R. COHEN, a citi' zen of the United States, residing at the city of New York, in the borough of Brooklyn and State of New York, have invented certain new and useful Improvements in Guards for Eyeglass-Mountings, of which the following is a full, clear, and exact description.

This invention relates to guards for eyeglass mountings, and has for its object the provision of an improved nose guard of such configuration that it may be more readily bent to fit the nose while affording a more sightly appearance than guards as heretofore constructed. This and other objects of my invention will be hereinafter referred to and the means whereby it is attained will be more particularly set forth in the claim appended hereto.

In the accompanying drawings wherein one embodiment of my invention is shown, and in which like reference characters designate like parts throughout the several views: Figure 1 is a perspective rear view of a pair of pince-nez glasses, provided with my novel guards. Fig. 2 is a detail of one of said guards. Fig. 3 is a section of a guard, taken on line IIIIII of Fig. 2. Fig. l is another view of said guard, showing the manner in which it is adapted to be bent. Fig. 5 is a fragmentary view of a guard, of a type commonly used, the guard proper being disposed substantially as is the improved guard shown in Fig. 2. Fig. 6 is a section of the guard shown in Fig. 5, taken on the line VIVI of Fig. 5; and Fig. 7 is another View of this guard, the view being similar to that of the improved guard shown in Fig. 4.

I prefer to provide my novel guard 1 in connection with a finger piece 2, but it is obvious that the guard may be used in any suitable mounting, whether such mounting be of the finger piece type or otherwise. In the form exemplified, the guard consists of two halves, the upper having substantially the form of a loop 2, and the lower of a strip or plate 3.

It has been customary heretofore to make nose guards in one of two forms, 2'. e., an initially, substantially fiat guard or an initially arcuately bent guard like that shown in Figs. 5, 6 and 7. The flat guard is, of course, adapted to be very readily bent to Specification of Letters Patent.

conform to the nose of the wearer, but it is open to two objections. It is not as attractive in appearance as the bent guard, the body of which is more or less gently curved throughout, as in the section shown in Fig. 6. Furthermore, the fiat guard has relatively sharp edges which dig into and tend to abrade the flesh against which they are disposed. Even if it be attempted to round the cutting edges of the guard, it is evident that owing to the relative thinness of the metal employed the radius of curvature must be practically insignificant, so that this does not remove the cutting edge in any substantial degree. It is highly desirable for a number of reasons to employ metal of very slight thickness in forming these parts. For example, the metal cominonly used is gold, which is expensive. Then again, lightness of weight is a desideratum; and again appearance must be considered; thick metal nose guards being highly objectionable from this last view point. Considering again the arcuately bent guard heretofore commonly used, while this guard is very sightly (until it is bent to conform to the Wearers nose) and while, as will. be seen upon an inspection of Fig. 6, it has a relatively long radius of curvature whereby it does not tend to' cut into the flesh at the edges thereof, nevertheless, it is open to a serious objection which F ig, 7 plainly illustrates. In order to fit the nose of the wearer it is usually necessary to bend these guards in a plurality of directions so that such a bend as is shown at 4: in Fig. 7 is apt to be required. Now when it is attempted to further bend an already arcuately bent plate or strip at right angles to the previously formed bending line, it is obvious that the metal must first unbend at the point where the bending lines cross, before the new bend can be formed. This results in a hump or kink 5 upon the body 3 of the guard which renders said guard more or less unsightly. I have found a means of overcoming the ditliculty in question, while at the same time preserving all the valuable characteristics of both the curved and fiat guards.

The body 3 of my improved guard is formed initially quite fiat, as shown in Fig. 3; but all around its edges is a struck-up bead or flared rib 6. .This bead is preferably formed by swaging or flaring the metal immediately adjacent the edges backwardly from the nose engaging surfaces of the guard. This permits of rounding the peripheral portions of the nose engaging surface as at 7 and it will be observed that by reason of the backwardly flared or swaged edges or bead 6, the radius of curvature of the surface 7 is relatively quite large compared to what it would be were the bead 6 not present. As shown, this radius of cur vature is practically twice the thickness of the sheet metal of which the guard is composed instead of being substantially equal to such thickness of metal, which it would be were it not for the bead 6. hen, however, it is desired to bend the guard as shown by dotted lines in Fig. 4, owing to the fact that practically the entire surface of the body of the guard is flat, as at 8, and that the beads 6 are adapted to stretch or to otherwise yield quite readily, the guard may be bent slightly in practically any direction without difficulty and no obj ectionably large kinks such as those shown at 5 in Fig. 7, will be formed.

In appearance, the guard with its neat bead is particularly attractive, much more so, in fact, than guards of the initially flat type. Furthermore, it is not only more readily bent than the arcuately bent guard shown in Figs. 5, 6 and 7 but after being bent is stronger and better adapted to resist inadvertent unbending; there being no rib or bead present in the device shown in Fig. 7, at the bending line in which are the'kinks 5, capable of aiding in resisting inadvertent deformation. The outturned edges 6 preferably are made relatively sharp, as shown, by thinning down the metal as the extreme edge is approached, since thereby the head is better adapted to stretch or otherwise yield. I particularly emphasize also the fact that the body of the guard is substantially flat or straight, more especially in the direction of its width. It may be added that if the guard be perforated as at 9, the

edges of this aperture are beaded and rounded substantially as at 7, in Fig. 3.

Having described my invention, I claim: In an eyeglass mounting, a nose guard comprising a body portion substantially straight in the direction of its width, said guard having a bead therearound outwardly directed from the nose engaging surface of the guard, said nose engaging surface having lts peripheral portions curved, the radius of curvature of said peripheral portions being greater than the thickness of the material of which said guard is composed.

In witness whereof, I subscribe my signature, in the presence of two witnesses.
